Our hotel has been replaced by a new, artsy type of Upper East Side style. And it's more than a tad French, too, courtesy of designer Jacques Grange. After a gut renovation, Grange infused the Mark which is split between hotel rooms, suites and residences with his signature bold, geometric, colour-splashy shapes and forms. Nowhere is that more evident than in the lobby, with the hotel's signature design statement: a marble floor in ultra long, thin black-and-white stripes, flanked by accents like polished-nickel Mattia Bonetti wall sconces and Paul Mathieu sofas. The 100 guest rooms and 50 suites carry that design theme forward, with Todd Eberle photographs, Quagliotti bed linens, coffered ceilings, and touch-screen panels controlling temperature, audio-visual components, and even the shades. "Studio rooms" and suites have custom kitchens, designed by Pierro Lissoni for Boffi, with black granite countertops and Miele dish washers.
